I need help in choosing a sub woofer for my home theatre. Configuration requirements- Receiver- Marantz SR6007 Fronts- Quad 11L Centre- Quad Rear- Wharfedales TV- Panasonic 42 in Room Size- 12 (TV side) x 18 x 10 feet Usage- Movies (60%), Music (30%), normal TV viewing (10%) I have been going through various AV forums and I my mind is almost made up in favor of SVS's subs. The unfortunate bit is that auditioning these is not possible. I am not too much of an audiophile, but I like the idea that whenever I listen to music or watch a movie, I should be have equipments that should be able to deliver quality stuff within my budget . Here are my queries- 1. Would be great if you could help me identify what sub woofer in the SVS stable would work best with my existing setup at a price range of USD 650 and below. I have the following options available: - PB1000 - SB1000 - SB12-NSD - PB12-NSD (tad above the budget) Purely on the basis of specs and some of user reviews that I have read, it seems that PB1000 is more suited to movie viewing (which is my main use) than SB1000, but frankly I don't have a clue. 2. Another point on which I need advice is that apparantly Quad 11Ls are fast speakers, so the sub I choose should not be out of sync with my current setup or show a perceptible lag while watching bass heavy movie scenes. 3. Lastly, would I be really missing something if I choose a sub that is rated 23 Hz as compared to another one rated 18 Hz? Is that 5 Hz gap really perceptible? Thanks a lot for all the help !!!
